The bottom towards water (flow) direction side of dam gate, for detecting the pressure of water in river when gate enables；As shown in figure 4, institute
The lower shaft of one end and steel dam anchor gate for stating torque protection instrument connects, and the connecting lever of the other end and steel dam anchor gate connects, for detecting lock
Door resistance suffered in the running；As shown in Figure 1, the pressure sensor and torque protection instrument with the programmable logic control
Device connection processed, the programmable logic controller (PLC) are connect with the frequency converter, and the frequency converter is connect with gate hoist, to adjust
Save the speed of service of headstock gear.
The pressure sensor uses the STS liquid measure for controlling automation Science and Technology Ltd. purchased from Shanghai outstanding person to be passed with pressure
Sensor DL-EX, DL or ATM23, the programmable logic controller (PLC) use siemens PLC SMART.
The working principle of the utility model are as follows: pressure signal is sent to programmable logic controller (PLC) and carried out by pressure sensor
Data processing, frequency converter connects headstock gear motor to drive double headstock gear work, while frequency converter receives Programmable logical controller
The data-signal of the pressure sensor of device processing, to automatically adjust the speed of service of headstock gear according to the size of pressure.It turns round
The torsion numerical value protected when can set safe operation inside instrument of trying hard to keep runs gate by force and makes when there is barrier to block gate
Torque value moment of torque protection instrument increases, and when torque value is greater than the set value, the movement of torque protection instrument export electric signal to can
Programmed logic controller, programmable logic controller (PLC) will call the police after detecting electric signal and stoppage protection, prevents that equipment is caused to damage
It is bad.
The specific course of work are as follows:
When the water level in river is in low water level, gate is run at this time, and pressure sensor can real-time detection water flow
The size of pressure is low-pressure, and the pressure value that pressure sensor detects at this time is less than 0.1Mpa, and pressure sensor is by pressure
Data transmission is to programmable logic controller (PLC), the low pressure force data of programmable logic controller (PLC) processing detection, while can be to frequency conversion
Device sends the electric signal according to the low speed operation after pressure treatment, and frequency converter can be by headstock gear after detecting low speed operation electric signal
Motor is maintained at low-speed operation mode, in gate operational process, if torsigraph detects that torsion crosses conference and is automatically stopped lock
